If you are thinking about a DNA test, then buy one from FamilyTreeDNA at www.familytreedna.com in August as there is a sale on most items. For males testing their surname line, a Y-37 test is down from $169 to $149. For males and females the autosomal (FamilyFinder) test is down from $79 to $59 and other tests are also on sale. If you already have a test with the company, then upgrades are cheaper in the sale too. It is well worth buying now. We recommend males with Y-37 upgrade to Y-67 or Y-111. The sale ends on 31st August.
If you have a long Oxfordshire family history (before 1875) then go to the Oxfordshire DNA project at www.familytreedna.com/public/oxfordshire and ‘join’ the project and buy a test at the same time.
